The U.S. Bureau of Land Management (BLM) filed an appeal with the U.S. Court of Appeals for the Ninth Circuit to reverse a Northern District of California judge’s preliminary injunction staying a final rule to delay compliance dates for the 2016 Waste Prevention Rule. The Waste Prevention Rule imposed methane emission reductions on oil and gas operations on federal and Indian lands. Industry groups and some states criticized the Rule as unnecessarily costly and duplicative of existing state regulations. Since the Northern District of California’s preliminary injunction, the District Court of Wyoming, which is handling an appeal of the 2016 Waste Prevention Rule filed by states and industry groups, stayed the Rule. Environmental groups appealed the stay to the Tenth Circuit and the states of Wyoming and Montana moved to dismiss the appeal for lack of jurisdiction. BLM is working on a final rule that would revise the 2016 Waste Prevention Rule’s requirements.
